Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm \E,Fe:/g  
Type: Double Bounces ;%Zn)etu  
The '****' denotes a possible internal focus }"AGX  
RMS is the RMS spot radius on axis at the primary wavelength. nNcmL/
(  
RMS values of 0.00 indicate that an accurate RMS <9Pf] G=  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is G `JXi/#`  
non-rotationally symmetric or uses non-standard surfaces.
